SPECIFICATION forming part of LetteISPatent No. 298,084, dated May 6, 1884.

Application tiled October 5, 1883. (No model.)

To a/ZZ whom it may concern,.-

Be it known that we, J oHN C. HARING and CHARLns H. COURT, residents of Jersey City, Hudson county, and State of New Jersey, have invented certain new and useful Improvements in Stylographic Fountain-Pens and we do hereby declare that the following is a clear and full description thereof, referencebeing had to the accompanying drawings, which form a part of this specification.

This invention relates to stylographic or fountain pens; and it consists in certain details of construction and combinations ofpart-s, as hereinafter pointed out and claimed.

The object ofthe invention is to simplify the construction and improve the operation of stylographic fountain-pens.

Figure l is a centra-l longitudinal section of au improved stylographic fountain-pen. Fig. 2 is a broken sectional view of the same. Fig. 3 is a central longitudinal section showing a modification of the spring for vibrating the needle-point. Fig. 4 is a broken sectional View of a stylographic fountain-pen, showing the spring and needle-holder within the end of the air-tube. Fig. 5 is a central longitudinal sectional view of a st-ylographic fountainpen, showing the air-tube and spring in one piece. Fig. 6 is a broken sectional view showing a modification of the needle-holder and Fig. 7 is a broken sectional view showing aV modification of the manner of supporting the spring needle-holder. Fig. 8 isa cross-section of a stylographic fountain-pen cutting through on the line e e, shown in Fig. 7.

Like letters of reference indicate corresponding parts in all of the figures.

The stylographic fountain-pen shown in the several guresconsists of the case A, air-tube C, and writing-point B. The extension-plug or spring-guideg is connected with the airtube C. The lower end of this plug guides and keeps the spring-tube It in position.

The tube h can be made of any suitable elastic or semi-elastic material not affected by the corrosive qualities of the ink, and which will admit of a spring to be formed thereof by cutting away, in any suitable manner, a suitable portion of the material forming said tube. The lower end of this tube is provided with a plug carrying the needle-point f,- but it may be dispensed with by substituting therefor a tube with a bottom of suitable thickness to receive and hold theneedle firmly therein. The spring canA also be formed by cutting a spiral channel around a solid cylindrical piece. This channel must be cut deep enough to pass the center of the cylinder, thereby-leaving atubular spring with solid ends.

The needle-holder shown in Fig. 3 consists of a plug, b, inserted in tube h. The tube is connected to the extension-piece g, while between this extension and needle-holder b a suitable -Aspring is placed for the purpose 0f vibrating the needle.

The air-tube C shown in Fig. 4t is provided with a plug, a, and needle-holder b, which is vibrated vby spring c.

The air-tube C shown in Fig. 5 is provided on its lower end with a suitable spring, formed by cutting therefrom a portion of the tube itself. The lower end 4of the spring is provided with a needle-holder, b, while the upper end of the air-tube is provided with a screw, D, for the purpose of extending the needle after the point wears away.

A. modification of the air-tube C and spring c is shown'in 6, whereinvthe plug a is forced into the tube in a suitable fixed position, after which a rubber or other suitable spring, c, can be inserted and kept in place by needle-holder b, theA needle-holder. being kept in position by friction, or by a pin, fi, working in slot 7c.

The needle-point can be advanced when worn away by removing the cap F and t'urning the air-tube C.

A modification of an adjustable spring-nee- `dle and holder is shown in Fig. 7, a cross-section of which is shown in Fig. V8.

Vhat we claim, and desire to secure by Letters Patent, is- Y 1. In a stylographic fountain-pen, the combination of the case, the air tube formed as described, to constitute a spring at its lower end, and the needle arranged within the case so as to have a bearing against said spring, whereby a vibratory or reciprocating movement is permitted to the needle, substantially as described. 1

2. In a stylographic fountain-pen, the case, the air-tube iuclosed thereby, said tube being IOO cub :may as described, to form u spring, and 5 away in part at its lower end to form :L spring,

beingprevidedwitllaplug (as g) near itslower l and a needle arranged, substantially as deend, and the needle arranged in the easing to scribed, t0 bearagainsb said spring, all in combem against said spring, all the parts iu com- 1 binatiou substantially as and for Bhe purpose 5 bination substantially as and for the purpose l set forth.
